Ubuntu – How to assign the key Super+M» to minimize all windows in Ubuntu 12.04

12.04keyboardshortcut-keysshortcutsunity

Everytime I press Super+M the Dash lens for music appears.

I have tried changing this behaviour using System Tools ▸ Keyboard ▸ Shortcuts ▸ Navigation ▸ Hide all windows to assign Super+M but it does not work.

I have also tried using CompizSetting to change the Unity shortcuts, but it seems that the Super+M shortcut is not defined here.

Any ideas?

A quick workaround would be to remove the Unity Music Lens.

Open a terminal (hit Ctrl+Alt+t) and type:

sudo apt-get remove unity-lens-music

You will be asked for your password. Type it in and hit Enter.

Then log out and log in again.

Now you can assing Super+M to minimize all windows through System Tools ▸ Keyboard ▸ Shortcuts ▸ Navigation ▸ Hide all windows

Ubuntu – How to change the binding of Windows key which runs Unity’s Dash

You can disable the super key using the command:

gconftool --set /desktop/unity/launcher/super_key_enable --type=bool 0

(Since GNOME 3 settings are in dconf instead of gconf, and unity became a plugin. The method thus became: dconf write /org/compiz/profiles/unity/plugins/unityshell/show-launcher '""')

Then you can define a keyboard shortcut with your preferred method to launch the following command:

dbus-send --type=method_call --dest=com.canonical.Unity2d /Dash com.canonical.Unity2d.Dash.activateHome

This will trigger Unity Home Dash

Ubuntu – change Synapse shortcut to Super/Windows key alone

See better answer below this one.

You must bind the action to the Super's scancode or keycode; normal hotkeys record the state of the modifier keys and throw away their keypress events; so you never see something that reacts to just pressing Alt, but instead to the A key plus the Alt key's recorded state.

The hotkey library in use is libgtkhotkey (0.2 on 12.04) and it doesn't support using the key press event from modifier's. You'd have to write your own patch to catch that and perhaps support such a thing in the signature format.

All tests with the existing signature format failed to produce anything but an error.
